1968 Honda CB350K0 Pistons & Rings

A standard-size piston kit is an option only after the CB350K0 cylinders have been measured. The kit covers one piston, including rings, pin and clips, so distinguish the size needed for each bore from the number of kits required.

1968 Honda CB350K0 · Pistons & Rings Buying guide

Confirm bore size before counting kits

The available kit combines a standard-size piston and its matching service pieces. It is suited to a measured rebuild plan, rather than choosing rings from the motorcycle’s year alone.

Parts to consider

Piston Kit with Piston Rings and Pin ~ Standard Size (07-0185) Standard-size piston kitOne piston with rings, pin and clips; two kits service both cylinders.View part

Order the assembly you actually need

Each kit includes a piston, piston rings, piston pin and clips for one cylinder. The piston reference is 13101-312-010. Confirm the complete kit against your rebuild plan before buying separate rings or pin-retaining parts that may duplicate its contents.

Let measurements determine the next step

Standard size is a dimensional choice, not a promise that an aged bore is ready for assembly. Ask the machinist to assess both cylinders before ordering. Follow the Honda manual and the supplied component instructions for clearances and assembly details.

Common buying questions

How many kits do I need for a complete CB350 twin?

Two kits cover the two pistons. Each kit includes the piston, rings, pin and clips for one cylinder; it is not packaged as a complete two-cylinder engine set.

Should I buy standard size if the bike still has its original engine?

Measure first. Original cases do not establish the current cylinder bore size, because a previous rebuild may have involved machining. Confirm standard-size suitability for each cylinder before placing the order.

Do I need separate piston-pin clips with this kit?

Clips are included in the kit’s stated contents. Check the kit against the work being done before adding more, particularly when only one piston is being serviced.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
